QWIIC

The SparkFun Qwiic Connect System is an ecosystem of I2C sensors, actuators, shields, and cables that make prototyping faster and less prone to error.

BENEFITS OF THE QWIIC CONNECT SYSTEM

The Qwiic Connect System is designed to keep your projects moving.

The Qwiic Connect System uses the Inter-integrated Circuit (I2C) Protocol. I2C protocol is intended to allow multiple “slave” digital integrated circuits (“chips”) to communicate with one or more “master” chips with a mere two wires. We've adapted that technology to unlock the following benefits:

No soldering between Qwiic breakout boards

Polarized connectors to prevent mistakes

Daisy chain capabilities to quickly add functionality

Let's take a closer look at the benefits...

Keep your soldering iron at bay.

Cables plug easily between boards making quick work of setting up a new prototype. We currently offer three different lengths of Qwiic cables as well as a breadboard friendly cable to connect any Qwiic enabled board to anything else. Initially you may need to solder headers onto the shield to connect your platform to the Qwiic system but once that’s done it’s plug and go!

Minimize your mistakes.

How many times have you swapped the SDA and SCL wires on your breadboard hoping the sensor will start working? The Qwiic connector is polarized so you know you’ll have it wired correctly, every time, from the start.

The PCB connector is part number SM04B-SRSS (Datasheet) or equivalent. The mating connector used on cables is part number SHR04V-S-B or equivalent. This is a common and low cost connector.

Expand with ease.

It’s time to leverage the power of the I2C bus! Most Qwiic boards will have two or more connectors on them allowing multiple devices to be connected.

Qwiic was predominantly designed for sensors but SparkFun are adding shields, sensors, actuators, and displays. You can also adapt your pre-existing SparkFun I2C products using the Qwiic Adapter. Check out the growing range of SparkFun QWIIC boards from Tronixlabs Australia below!
